As you may already know, thesis is an obligatory part of your degree and every student has to do it at some point of their studies. I felt intrigued when I got to know that the majority of students in Finland write their theses as a practical case studies for different companies. It means that a company has a problem to solve or theory to be tested and they give this job to a student. In this way, companies get solutions for their problems without need to hire a person specifically for that task and student get to apply their knowledge in real work-life case already before graduation + possibly make some money.
